N O T I C E

Always disconnect power to the instrument before electrical connections are made.

Obey all safety statements while connections are made to the instrument.

Electrostatic discharge (ESD) considerations

N O T I C E

Potential Instrument Damage. Delicate internal electronic components can be damaged by static

electricity, resulting in degraded performance or eventual failure.

Refer to the steps in this procedure to prevent ESD damage to the instrument:

• Touch an earth-grounded metal surface such as the chassis of an instrument, a metal conduit or

pipe to discharge static electricity from the body.

• Avoid excessive movement. Transport static-sensitive components in anti-static containers or

packages.

• Wear a wrist strap connected by a wire to earth ground.

• Work in a static-safe area with anti-static floor pads and work bench pads.

Electrical connections

Connect probes, external power, cables and USB devices as shown in Figure 2 and Figure 3.

Maintenance

W A R N I N G

Multiple hazards. Do not disassemble the instrument for maintenance or service. If the internal components must

be cleaned or repaired, contact the manufacturer.

C A U T I O N

Personal injury hazard. Only qualified personnel should conduct the tasks described in this section of the manual.

Clean the instrument exterior

The instrument exterior can be cleaned as needed. To avoid human exposure to potentially

dangerous chemicals, make sure to clean the touchscreen immediately after contact with chemicals.

N O T I C E

Do not leave visible moisture on the instrument or touchscreen. Moisture can penetrate the touchscreen and

damage electronics inside.

1. Put the cap on the sample air intake nozzle.

2. Spray a mild cleaning solution on a soft cloth. Wipe the outside of the instrument carefully.

3. Use a soft, dry cloth to wipe the touchscreen surface. If needed, moisten the soft cloth with a mild

cleaning solution.

Set the count to zero

Do this procedure after unexpectedly high particle counts. This procedure will verify that the particle

counter works correctly and will remove residual particles.

1. Put the zero-count filter on the intake tube. Refer to Figure 1 on page 8.

2. Turn on the unit and log in if needed.

3. Push SAMPLE.

16

English

4. Push RUN.

5. Repeat the process until the particle counts return to zero.

Charge the batteries in the particle counter

Batteries in the 3400 will begin to charge when the AC power cord is connected. A complete charge

in the instrument takes approximately 10 hours. The battery is considered to be fully charged when

they display shows the charge between 95% and 100%.

Prerequisite: Install the batteries in the instrument. Refer to Install the batteries on page 10.

N O T I C E

Discard the used batteries according to local regulations or contact the manufacturer. Do not put exhausted

batteries in the domestic waste.

1. Attach the power supply to the unit. Refer to Figure 3 on page 10.

2. Connect the unit power supply to the external power through the AC power adapter.

The battery status light will show the level of power in the battery. Refer to Table 3.

Table 3 Battery LED color indications
